These are a couple of the Autobot and Decepticon pendants that I've made. They are a little larger than a US quarter, but smaller than a 50cent piece. I actually freehanded these, so the lines are a tad bit wavy...
I am super happy with the way they came out
EDIT on Nov. 7: These pendants are made out of plastic.
I am open for commissions. These pendants are for sale at Etsy: [link]
